Thanks for the response, happy to hear I don't have to send it back :)

For the 12v issue, I applied it to the 5v pin, no other power would have been applied from usb or ethernet.

Where did you apply 12V to? Maybe it can be fixed by changing a component or two.

No, you are good. This is a factory patch applied in hardware revision M1. It is mentioned in the hardware revision changes:

ESP32 / New ESP32-POE-ISO - was I sold...
Last post by chrismacp - January 23, 2026, 12:36:28 PM
Hi,

I recently had to buy a new ESP32-POE-ISO as I mistakenly applied 12v to my previous one for a few seconds and it no longer functions (although LEDs do come on).

After unpacking the new unit I noticed it had an extra component ("570F KE") connecting capacitor C26+ to the black box component (DCDC1 I think). I couldn't find a match online to the extra component "570F KE".

I was wondering if this component was to be expected or if I should return this unit? I don't really want something that someone has modified.

Note: I didn't purchase directly from Olimex, but another store, in Germany.

Try with this code (download the whole repo):

https://github.com/OLIMEX/MOD-LCD2.8RTP/tree/master/SOFTWARE/Arduino/graphicstest_olimex_NS2009

Make sure PSRAM is enabled in your board selection options (this is specific for WROVER boards).

ESP32-POE-ISO-WROVER rev L + MOD-LCD2.8RTO rev D the Display only shows backlight LED. I could not activate the display with text. I have tried a lot of variants in the code. Are there any special things to make it work?

the uext gpio set up is:
| UEXT-Pin | Signal | ESP32-GPIO | Funktion |
|----------|--------|------------|----------|
| 1 | 3.3V | 3.3V | Stromversorgung |
| 2 | GND | GND | Masse |
| 7 | **MISO** | **GPIO19** | **D/C (als Output!)** |
| 8 | MOSI | GPIO23 | SPI MOSI |
| 9 | CLK | GPIO18 | SPI CLK |
| 10 | SSEL | GPIO5 | SPI CS |

Quote from: sndsgd on November 13, 2025, 01:09:58 PMIf you want to get dimensions while you're waiting for the hardware to arrive, you can get them from the kicad files on github: https://github.com/OLIMEX/iMX8MP-SOM-EVB.

It is exactly what I tried to do, but surely I have done mistakes of millimeters here and there.
I was waiting for having my hands on the actual device for correcting the positions, but my work condition changed, and I don't think I will make a case for the device nor that I will have the device at all.
Please feel free to take the draft linked above, improve it and push it upstream.

UEXT / Re: MOD-IRDA faulty ?
Last post by LubOlimex - January 09, 2026, 03:31:43 PM
Indeed, thank you for your research. I got back to testing this and the distance is up to 2.5-3m which is unexpectedly low, we determined that the LED is simply small for better distance. The engineers wanted to save space but it is not worth it. In future we would switch to 5mm IR333-A, which seems to improve the range to around 10m which is much better. Thank you for reporting this.

We have no experience with it. Only used the OSS CAD Suite.

FPGA / toolchain for GateMateA1-EVB
Last post by mastupristi - January 04, 2026, 06:12:38 PM
Hello,
The document ug1002 "Toolchain Installation User Guide" is listed on your website.

Inside I find:


Following the directions, however, I find this:
https://colognechip.com/programmable-logic/gatemate/toolchain/

It seems that document ug1002 describes the legacy toolchain called cc-toolchain-linux.tar.gz,
but as you can see on the page, the most recent toolchain is oss-cad-suite-linux.

However, I cannot find any usable examples in this new toolchain.

I found some examples (perhaps) that could be useful here: https://github.com/YosysHQ/prjpeppercorn-test-cases

What do you think about using the new toolchain?
Do you have any quick guides on this? Or even just suggestions?

regards
Max
